Why is this an issue?
Optional chaining allows to safely access nested properties or methods of an object without having to check for the existence of each intermediate
property manually. It provides a concise and safe way to access nested properties or methods without having to write complex and error-prone
null/undefined checks.
This rule flags logical operations that can be safely replaced with the ?. optional chaining operator.
How to fix it
Replace with ?. optional chaining the logical expression that checks for null/undefined before accessing the
property of an object.
Code examples
Noncompliant code example
function foo(param) {
if (param && param.value) {
bar(param.value);
}
}
Compliant solution
function foo(param) {
if (param?.value) {
bar(param.value);
}
}
